Happy Friday, Houston! Summer may have taken a little time to kick off this year, but we’re definitely locked in the doldrums now, with what you would expect this time of year. Let’s jump into it.
Looking at weather maps this morning, we see a pretty rich area of precipitable water (PWAT) approaching the Coastal Bend to our south. In English, that means there’s going to be gradually increasing amounts of moisture available for thunderstorms to pop up this afternoon.

So while it has been mostly quiet the last couple days, I expect we’ll see just a few more pop-up storms this afternoon (perhaps this morning along the coast). The best chance for greater coverage of afternoon hit/miss storms will be west of I-45 and south of I-10. The further north and east you go, the slightly drier the air mass stays today, so that should keep pop-up storms to a minimum. High temperatures will remain hot, into the low 90s, with heat indices into the low 100s. Read More…
Good morning. It’s Thursday. So we’re edging closer to the weekend, Houston!
Houston’s not directly under a ridge of high pressure today, but we’re close enough that any rain showers that do develop should be fairly isolated. For the most part we’re going to be hot, humid and sunny with highs in the low- to mid-90s. Heat index values may climb into the low 100s.

Good morning. A few streamer showers are moving northward quickly through Houston this morning, but with high pressure building these rains should come to an end later this morning.
TODAY through FRIDAY
It’s not like the suffocating ridges of high pressure that Houston sometimes sees during the summer (thank goodness) but moderately high pressure should keep the region mostly dry, sunny and warm during the next three days. Look for high temperatures in the low- to mid-90s with only some isolated showers.

Good morning. If you’re tired of the heat already there’s one tiny bit of good news. The summer solstice occurred on Monday (at 5:34pm CT to be precise) so from here on out the days only get shorter, and the Sun doesn’t climb so high in the sky. Unfortunately for us living along the Gulf coast, temperatures lag considerably behind shorter days, so our warmest period does not come until late July and August.
High pressure is building southward, but there’s enough moisture for some showers to develop later today, especially as the sea breeze moves in early this afternoon. Like on Monday the showers will be scattered, but could quickly drop 0.5 to 1.0 inch of rain over some areas. Much of Houston should remain partly sunny and hot, however, with highs in the low 90s. Rain chances end by or before sunset.
WEDNESDAY and THURSDAY
With high pressure in place for the middle of the week I expect mostly sunny skies, highs in the low- to mid-90s, and lows in the mid-70s. This will be classic, humid, summer-like weather for Houston.

Good morning. Houston remains at the southern edge of a high pressure system, which should build over the metro region during the next couple of days. We’ll see some rain chances before that happens.
I suspect rain chances later this afternoon will be similar to those on Sunday. While much of the area saw little or no rain, pockets of the city saw 0.5 to 1.0 inch of rain Sunday during primarily afternoon thunderstorms. Highs will likely climb into the low 90s.
This high pressure over the southeastern United States has kept a tropical system away from the Texas coast, and that’s probably a good thing. Tropical Storm Danielle formed in the southern Bay of Campeche this morning, but proximity to land is likely to prevent it from strengthening too much. Had it been allowed to move north toward the Texas coast, it would have had more time for development over open water. In any case, the system is going to be a rainmaker for Mexico, and is also notable as the earliest fourth tropical storm on record, beating Debby 2012 (June 23) and Dennis 2005 (July 5). It’s still not clear to me that this augurs a particularly bad overall hurricane season, because all the systems we’ve seen form have been fairly weak tropical storms.
